Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a tool for cutting mortar injection grooves on the end face of an ALC plate into a desired cross-sectional shape.

[Conventional technology and its problems]

In recent years, ALC boards (lightweight aerated concrete panels) have been widely used as exterior wall construction materials. this
A method described in JP-A-57-137584 was devised as a construction method for forming openings for windows and the like in an outer wall made of ALC boards. That is, in this construction method, as shown in FIG. 5, ALC boards 1 are placed apart by the width of the opening A, and side frames 2, 2 having substantially the same shape are applied to the opposing end surfaces, respectively. The upper frame 3 and the lower frame 4 are welded to the pair of side frames 2 and 2, separated by the vertical dimension of the opening A, and then the ALC board 1 is installed on the upper part of the upper frame 3 and the lower part of the lower frame 4, and the ALC board 1 of frame 4
An opening A is formed in the outer wall made of the ALC board by inserting an insertion line into the mortar injection hole 5 provided on the end faces of the two and injecting mortar.

Incidentally, the ALC board 1 is manufactured and sold by various companies, and the standards for size etc. are unified, but the standards for the mortar injection groove 5 formed on the end face are not unified. That is, the cross-sectional shapes of the grooves 5 of the ALC plates of each company are various.

Therefore, in the opening forming method described above, it is necessary to manufacture the side frames 2 each having a cross-sectional shape that matches the cross-sectional shape of the groove 5 of each company.

The purpose of this invention is to keep the above points in mind and to
By cutting grooves on the end face of the plate, the side frame with a single cross-sectional shape can be made compatible with all ALC plates from various companies.

[Means for solving problems]

In order to achieve the above object, this invention provides an end face groove cutting tool for an ALC plate, and the tool has a support piece perpendicular to the axial direction attached to the tip of the gripping rod, and one part of this support piece. A guide piece in the axial direction is provided at the side end, and a blade having the desired cross-sectional shape of the mortar injection groove on the end face of the ALC board is provided at the lower edge of the support piece, and the distance from the guide piece to the blade is set as described above.
This is made to match the distance from the side surface of the ALC plate to the injection groove with the desired cross-sectional shape.

[Effect]

To obtain a groove with the required cross section using this tool,
First, apply the blade to the end groove of the ALC plate and place the guide piece against the side of the ALC plate, and use the gripping rod to slide the guide piece along the side of the ALC plate while pressing the blade into the groove. Then, the inner surface of the groove is cut with a blade to make the cross-sectional shape of the groove into the shape of the blade.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

〔Example〕

As shown in FIG. 1, a forked metal piece 11 is attached to the tip of the gripping rod 10 so as to protrude, and a supporting piece 12 perpendicular to the axial direction of the gripping rod 10 is integrally attached between the ends of the metal piece 11. establish. The guide plate 13 in the axial direction is provided at one end of the support piece 12, and the support piece 12
A blade 14 with a straight cutting edge is formed at the lower edge of the blade. The cutting edge width T of this blade 14 is assumed to be the same as the inner width t of the side piece of the side frame 2 in FIG.

A screw hole 15 is formed in the center of the support piece 12, into which a tightening screw 16 can be screwed. A replaceable blade plate 17 is applied to the support piece 12, and by passing the screw 16 through the long hole 18 into the blade plate 17 and screwing it into the hole 15 and tightening,
The blade plate 17 is fixed to the support piece 12 at a desired position.
The lower edge of the blade plate 17 has a groove 5 in the side frame 2 shown in FIG.
Blade 1 with a cross-sectional shape (circular in the example) of the insertion part
9 is formed, and as shown in FIG. 3, the distance a from the guide piece 13 to this blade 19 is made to match the distance a' from the side surface of the ALC plate 1 to the injection groove 5.

A folding piece 20 is provided on the upper edge of the blade plate 17 so as to protrude forward. A fastening bolt 22 is rotatably fitted into a central notch 21 of the folding piece 20. The bolt 22 is screwed into a nut 23 fixed to the support piece 12. By turning the bolt 22, the blade 19 and the support piece 12 are fastened to each other.
Adjust the amount of protrusion from the bottom edge.

In addition, in the figure, 24 is a nut for fixing the bolt 22 to the folded piece 20, which is fixed to the bolt 22.

The embodiment is configured as described above, and its operation will be explained next.

First, if the side frame 2 has a side piece, as shown in FIG. 14 is pressed and slid against the side surface of the ALC board 1 and cut to form a recess 25 of a desired width. The side pieces of the frame 2 fit snugly into this recess 25.

Next, as shown in FIGS. 2 and 3, the blade plate 1
7, and apply the blade 19 to the end groove 5 of the ALC board 1, and the guide piece 13 to the ALC board 1.
Place the guide piece 1 on the side and hold the grip bar 10.
3 along the side surface of the ALC plate, the blade 19 is slid into pressure contact with the groove 5, and the blade 19 cuts the inner surface of the groove to make the cross-sectional shape of the groove 5 into the shape of the blade 19. This shape is the shape of the groove fitting part of the frame 2, so that this fitting part fits snugly into the groove 5.

In this way, the end face groove 5 of each company's ALC board 1 is made into a desired cross-sectional shape that matches the frame 2, and thereafter, the opening A is formed in the same manner as described above.

Note that, as in the embodiment, blades 19' may be formed on both sides of the blade 19 of the blade plate 17 to cut the ALC plate end faces on both sides of the groove 5 as necessary.

In addition, in the embodiment, the side cutting blade 1 is attached to the support piece 12.
4 is formed, but like the blade plate 17, this blade 14 may also be removed as a separate piece from the support piece 12, and the amount of protrusion may be adjustable.

[Effect of idea]

This idea is constructed as described above, and the mortar groove on the ALC end face can be cut into the desired cross-sectional shape, so one type of opening component frame can be applied to all ALC plates from different manufacturers. This has the effect of reducing construction costs for openings and the like.
